Uniformly distributed ZnO nano-rods (NRs) with diameters in nano-scale have been successfully grown two stages; the first at annealing temperature (250–300 °C) for seed layer preparation on glass substrate by using sol gel technique and second low (90–95 aqueous chemical growth (ACG) method. The same prepared thin film samples were surface of silver wire (0.25 mm diameters) to produce electrochemical nano-sensors. structure morphology will be evaluated XRD, Scanning electron microscope SEM....
Abstract Silica phosphate glasses strengthened with a calcium oxide modifier and doped different concentrations (0%, 0.5%, 1%, 1.5 mol%) of praseodymium (Pr 3+ ) were synthesized by sol–gel method. The absence sharp peaks in the X-ray diffraction spectra confirms noncrystallinity glasses. Higher doping indicates increasing optical bandgaps due to Burstein–Moss shift, which also reflects on structural disorders at absorption tails, as validated Urbach’s rule. density increases subsequent...
Abstract The focus of the current work is study effect photo-catalytic activity ZnO nanoparticles. photocatalytic destruction methylene blue dye, a common water contaminant, was used to assess efficiency nanoparticles from its aqueous solution by using thin film under UV light and laser irradiation. Sol–gel methods prepared nanoparticle films. X-ray diffraction field-emitted scanning electron microscope were utilized examine structure produced An extended characterization laser-based...
ZnO is distinguished multifunctional material that has wide applications in biochemical sensor devices. For extracellular measurements, Zinc oxide nano-rods will be deposited on conducting plastic substrate with annealing temperature 150 °C (ZNRP150) and silver wire 250 (ZNRW250), for the glucose concentration determination functionalized ZNR-coated biosensors. It was performed phosphate buffer saline (PBS) over range from 1 µM to 10 mM human blood plasma. The prepared samples crystal...
Pure barium titanate BaTiO3 (BT) and BT doped with two dierent transition elements Fe 3+ Ni 2+ at 5 mol.% (BT5Fe BT5Ni, respectively) as constant concentration in powder form have been prepared by sol gel method using acetate, titanium(IV) n-butoxide, iron nickel nitrates precursor materials.The microstructure of the inuence dopants on it were investigated X-ray diraction Fourier transform infrared spectroscopy.X-ray shows that tetragonal phase is dominant for pure sintered 4 h 800 • C....
Nano-structure Barium Titanate (BaTiO 3 ) doped with 1 mole% Sm 3+ and Gd ions have been synthesized by modified sol-gel process. The tetragonal perovskite structure has demonstrated means of X-ray diffraction selected area electron obtained high resolution transmission microscopy. XRD HRTEM used for estimation the grain size, which found to be around 38.36 33.26 nm. scanning microscope micrographs asserted formation agglomerated particles, is characteristic many nano-systems. green emission...
A series of silica-phosphate nano-composites prepared as a host thin films Physical Properties Nano-Composite Silica-Phosphate Thin Film Prepared by Sol Gel Technique and doped with different concentrations Er3+ ions have been synthesized using tetraesoxysilane TEOS, triethylphosphate TEP erbium nitrate precursor sources silica, phosphorus oxides. The structural properties pure were studied, x-ray diffraction (XRD) Fourier Transform Infrared (FTIR). morphology was characterized Scanning...
The sol–gel technique is a very flexible, relatively simple, and low-cost method to fabricate many different innovative photonic structures characterized by specific functionalities. During synthesis, starting from the molecular level, compounds or composites with well controlled composition can be obtained as thin films, powders monoliths. These materials used prepare such waveguides, crystals, coatings, bulk glasses including spheres, rings other geometries exploited in optical resonators...
